Hi Marie & welcome to our forum 
! - Chucky might still find your question, but praps I can help.
I’m not sure what exactly you mean tho - the needles are put all over the body, more than in your face/head.
I’m on my 3rd stint of acupuncture (9x negligently, 1x supposedly for fibro, and now real Chinese 16x and running). In each of these 1 needle was put at the top of my scalp, and often one in my forehead, praps sinuses if they were acting up, once 2 needles in one ear. But every time about 20-24 needles were used altogether. Until the cupping by the Chinese acupuncturist wasn’t helping my energy/fatigue, when she decided to put needles next to my spine (24-28) which has made a lot of difference, started build up my energy properly. The other two stints didn’t help at all, just hurt - but acupuncture doesn’t hurt most people at all. It’s got a certain evidence for fibromyalgia, so definitely worth a try, but most who have had success with it recommend to make sure it’s someone really good who does it. Quite a few people recommend Chinese acupuncture, not the watered down Western modification, but some don’t tolerate the thicker needles. For me some (about 4 of the 46) hurt a bit more while putting in, but less once they’re in and after…
Oh, I forgot: you can track the mixed success on my blog
